Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

Buy an eSIM with a contact person like here instead. I bought a supposedly unlimited SIM card at the airport that stopped working after 7 days, and I couldn't find anyone to help me because the provider only operates at airports. The eSIM has worked perfectly for the last 20 days.

The internet was incredibly fast and the signal was consistent. It was easy to use. Throughout the trip, our group used both eSIMs and roaming, and our internet was the fastest and most stable. We used GPS constantly for 9 days and were still able to use TikTok, Instagram, ChatGPT, and Gemini the whole time.

The signal is excellent and fairly fast in Tokyo and other areas of Japan, and the price is very affordable. Highly recommended.
